Project description
Looking up to find water below
Beneath Earth’s surface, there’s water – in the cracks and spaces in soil, sand and rock. While the ability to detect groundwater is crucial, there is still no data source worldwide that operationally provides information on changing groundwater resources in a consistent way, observation-based, and with global coverage. To fill this gap, the EU-funded G3P project will bring together science and industry across Europe to show groundwater storage variations using GRACE and GRACE-FO satellite gravity data. GRACE was a 2002-2017 satellite mission. GRACE-FO followed in 2018 to provide continuity for the GRACE data set. While the project’s approach is not new, it is global in extent and utmost based on satellite observation data instead of simulated data.
Objective
Groundwater is one of the most important freshwater resources for mankind and for ecosystems. Assessing groundwater resources and developing sustainable water management plans based on this resource is a major field of activity for science, water authorities and consultancies worldwide. Due to its fundamental role in the Earth’s water and energy cycles, groundwater has been declared as an Essential Climate Variable (ECV) by GCOS, the Global Climate Observing System. The Copernicus Services, however, do not yet deliver data on this fundamental resource, nor is there any other data source worldwide that operationally provides information on changing groundwater resources in a consistent way, observation-based, and with global coverage. This gap will be closed by G3P, the Global Gravity-based Groundwater Product.
The G3P consortium combines key expertise from science and industry across Europe that optimally allows to (1) capitalize from the unique capability of GRACE and GRACE-FO satellite gravimetry as the only remote sensing technology to monitor subsurface mass variations and thus groundwater storage change for large areas, (2) incorporate and advance a wealth of products on storage compartments of the water cycle that are part of the Copernicus portfolio, and (3) disseminate unprecedented information on changing groundwater storage to the global and European user communities, including a European use case as a demonstrator for industry potential in the water sector. In combination, the G3P development is a novel and cross-cutting extension of the Copernicus portfolio towards essential information on the changing state of water resources at European and global scales. G3P is timely given the recent launch of GRACE-FO that opens up the chance for gravity-based time series with sufficient length to monitor climate-induced and human-induced processes over more than 20 years, and to boost European space technology on board these satellites.
